Title: Automatic cold starting control for I.C. vehicle engine - is disconnected for frequent starts in short journey traffic conditions
Inventor: HINTEREKER HANS
IPC: F02M1/12
Filed: 1974-04-09
Abstract: The carburettor has a cold starting throttle controlled by a bimetal strip in the ignition circuit. In the cold position this increases the mixture richness and reduces it after the bimetal has been heated by the ignition circuit current. The bimetal closes again when the ignition is switched off. This causes the engine to start on a rich mixture even when it ahs been switched off only a short time. A manual switch with two contacts breaks the connection between ignition and bimetal and makes a permanent connection between battery and bimetal. This prevents the bimetal's returning to cold start conditions and can be used when the engine is to be stopped and started frequently in traffic conditions.

Title: Electrostatic powder spraying for pre-heated metal tubes - tube length is heated to different temperatures
Inventor: ZIMNIK WALTER DIPL ING DR
IPC: B05D3/02
Filed: 1974-10-10
Abstract: During the electrostatic spraying of powderized materials onto pre-heated metal tubes, a relative speed in a longitudinal direction of the tube exists between it and the spray unit. the length of the tube is pre-heated to different temperatures, so that the tube end, where the spraying commences, has the lowest temperature. The temperature increases over the length of the tube, in a linear way, until a maximum value is reached, so that the temperature is always constant at the point of spraying. The optimal qualities of the powdered material is thereby maintained since the heating is kept within narrow tolerances.
